Abstract
recently, the wireless sensor networks has been used extensively in different domains. Form healthcare to warfare, and indoor spaces to outdoor ones, we can see the existence of sensor networks everywhere. But secure communication is a very important requirement in wireless sensor networks, and how to share the security group key between the sensor nodes becomes the major problem. In this paper, a secure, efficient and authenticated group key agreement protocol for wireless sensor networks is proposed by using node-ID and bilinear pairings. Comparing with previous group key management schemes for wireless sensor networks, our scheme can against passive and active attacks, against node compromised attack, ensure the backward and forward security, and improve network computing complexity.
